Mangostin derived from mangosteen was identiÞed as a mosquito sterol carrier protein-2 inhibitor via high throughput insecticide screening. -Mangostin was tested for its larvicidal activity against third instar larvae of six mosquito species, and the median lethal concentration values range from 0.84 to 2.90 ppm. The residual larvicidal activity of -mangostin was examined under semiÞeld conditi...

The best way to control mosquito borne diseases is to control the mosquito population. The present study was executed to evaluate the mosquito larvicidal activity of Nicotiana plumbaginifolia leaves against malarial vector Anopheles stephensi.Crude extracts and three different solvent extracts were bio-assayed against An. stephensi larvae. LC50 and LC90 values were determined appropriately. Qua...

Abstract: Background: Synthesis of silver nanoparticles (AgNPs) using green plants is important for biocompatibility, reduced hazards, policy and eco-friendliness. Materials Methods: In this study, a leaf extract Solanum indicum associated AgNPs were used to examine larvicidal properties other biological activities. AgNP forms characterized with scanning electron- microscopy (SEM), Fourier Tran...

The adverse effects of chemical insecticides-based intervention measures for the control of mosquito vectors have received wide public apprehension because of several problems like insecticide resistance, resurgence of pest species, environmental pollution, toxic hazards to humans, and non-target organisms. These problems have necessitated the need to explore and develop alternative strategies ...

The aim of this work was to study the larvicidal activity of Lippia sidoides essential oil against Aedes aegypti larvae. The essential oil and its hydrolate (saturated solution of essential oil in water) were obtained by vapor extraction and their chemical composition determined by GL-chromatography coupled to mass spectroscopy. Bioassays were run with the essential oil, pure and diluted hydrol...

Purpose: To synthesize Mannich base imidazole derivatives, and evaluate their antimicrobial, nematicidal and larvicidal properties . Methods: Compounds 1a-g and 2a-g were prepared using a Mannich condensation method. The chemical structures of compounds 2a-g were confirmed by Fourier transform infrared spectroscopy (IR), proton nuclear magnetic resonance (H-NMR), carbon nuclear magnetic resonan...

Microcos paniculata traditionally known as ‘Kathgua or Fattashi’ in Bangladesh is widely used for the treatment of various ailments including colds ,diarrhea, hepatitis, heat stroke, dyspepsia, wound healing, fever and as an insecticide. Hence, the present study was designed to investigate the antibacterial, toxicity & 4 th instar Culex quinquefasciatus mosquito larvicidal activities of fruit e...

Although most algae are nutritious food for mosquito larvae, some species kill the larvae when ingested in large quantities. Cyanobacteria (blue-green algae) that kill larvae do so by virtue of toxicity. While blue-green algae toxins may offer possibilities for delivery as larvicides, the toxicity of live blue-green algae does not seem consistent enough for live algae to be useful for mosquito ...

background : thymol and carvacrol have previously demonstrated larvicidal activity against aedes aegypti (diptera: culicidae). in view of this fact, it was of our interest to obtain synthetic derivatives and evaluate their larvicidal ac­tivity on ae. aegypti larvae. methods : structural modifications were performed on thymol and carvacrol in an effort to understand the functional groups necessa...
